Background: The aims of this study were compare the serum visfatin and resistin levels between endometrial cancer (EC) patients and controls and evaluate their power to predict prognosis. Materials and Methods: This prospective study was conducted between March 2013 to June 2014 on the Gynecologic Oncology Department of the University of Selcuk, Konya, Turkey. A total of 42 EC patients and 42 controls were included and assessed for differences in serum visfatin and resistin levels, along with prognostic factors. Results: Endometrial cancer patients had significantly higher visfatin levels than control s (p: 0.011), associated with deep myometrial invasion (p: 0.019). In contrast the serum level of resistin did not significantly differ between EC patients and controls (p: 0.362). However, high resistin level in EC patients was associated with increase lymph node metastasis (p: 0.009). On logistic regression analysis, we found that serum visfatin elevation was associated with risk of myometrial invasion (OR: 1,091; 95%CI: 1.021-1.166; p: 0.010) and serum resistin with risk of lymph node metastasis (OR: 1.018; 95%CI: 1.000-1.035; p: 0.046). For myometrial invasion prediction, a serum visfatin level greater than 26.8 ng/mL demonstrated a sensitivity and specificity of 66.6 % and 96.4%, respectively. For lymph node metastasis prediction, the best cut-off for serum resistin level was 599ng/mL. A serum resistin level greater than this demonstrated a sensitivity and specificity of 87.5% and 77.1%, respectively. Conclusions: Our data suggest that serum visfatin is elevated in patients with EC and serum visfatin and resistin levels could be used to predict the risk of advance stage lesions.
Systemic sclerosis (SSc) is an autoimmune connective tissue disease with multisystem involvement. An increased incidence of cancer in SSc patients compared with the general population has been reported in several reports. Our aims in this study were to determine the most common malignancies and to investigate the possible risk factors for the development of malignancy in patients with SSc. Three hundred forty SSc patients from 13 centers were included to the study. Data of the patients were obtained by evaluating their medical records retrospectively. A total of 340 patients with SSc were evaluated. Twenty-five of the patients had 19 different types of malignancy. Bladder cancer was the most common type of cancer with four patients and was followed by breast cancer with three patients, and cervix cancer and ovarian cancer with two patients each. Other types of cancers such as squamous cell skin cancer, adenocancer with an unknown origin, multiple myeloma, chronic myeloid leukemia, papillary thyroid cancer, larynx cancer, non-small cell lung cancer, follicular type non-Hodgkin lymphoma (NHL), endometrium cancer, colon cancer, uterus cancer, neuroendocrine tumor, glioblastoma multiforme, and soft tissue sarcoma were diagnosed in one patient each. The only cancer type that showed an association with cyclophosphamide dose was bladder carcinoma. Other malignancies did not show a correlation with age, sex, smoking, type and duration of the disease, autoantibodies, organ involvement, and dose and duration of cyclophosphamide therapy. Cancer may develop in any organ in patients with SSc. Continuous screening of the patients during a follow-up period is necessary for the early detection of the tumor development.
Introduction: The purpose of this study was to investigate group B streptococcus (GBS) colonization, to compare the methods, to determine the relationship between GBS carriage and risk factors, and to genotype the GBS isolates. Methodology: Recto-vaginal swab specimens were obtained from 500 women, and a questionnaire was administered to each to assess their risk factors for GBS carriage. A culture, GBS antigen test, and polymerase chain reaction (PCR) were performed on all samples. Antibiotic susceptibility testing was performed, and the clonal relationship was determined by pulsed-field gel electrophoresis (PFGE) on all viable isolates. Results: Of the 500 women, sixty-eight (13.6%) women were GBS carriers, of whom 9.8% were pregnant and 16.5% not. There was a significant difference between GBS carriage and history of premature rupture of membrane (PROM). GBS was isolated from 65 (13%) samples. GBS was positive in 70 (14%) samples by antigen test and in 62 (12.4%) by PCR. Sixty-eight of the 70 positive antigen tests were confirmed by PCR or culture. Fifty-five isolates were resistant to tetracycline, 16 to erythromycin and clindamycin, and 13 to levofloxacin. Thirteen different pulsotypes and 17 sporadic strains were determined by PFGE. Conclusions: GBS carriage rate in non-pregnant women was higher than in pregnant women. The GBS antigen test was more sensitive than culture and PCR. GBS isolates did not originate from a single clone and contained sporadic strains. There was a significant difference between GBS carriage and history of PROM. Epidemiologic data obtained in this study will help future studies.
We evaluated the concentrations of human epididymis secretory protein E4 (HE4) and Ca-125 in relation to clinicopathologic features in patients with endometrial cancer and premalignant endometrial lesions. Women with abnormal uterine bleeding (n = 167) who underwent endometrial sampling were divided into four groups. Group 1: endometrial cancer (n = 68), group 2: atypical endometrial hyperplasia (n = 12), group 3: endometrial hyperplasia without atypia (n = 39) and group 4: controls (n = 48). Women with endometrial cancer exhibited higher concentrations of HE4 levels than controls (91.4 pmol/L vs. 46.2 pmol/L, p < 0.001). HE4 levels were significantly higher in patients with lymphatic involvement, deep myometrial invasion, lymphovascular space involvement and non-endometrioid histology (p < 0.001). The sensitivity, specificity, positive and negative predictive values for HE4 in detecting endometrial cancer were 72.7%, 84.4%, 80% and 78.4%, respectively. Preoperative HE4 levels are more elevated in women with endometrial cancer than those with benign endometrium as well as in women with prognostic high-risk factors with endometrial cancer. HE4 may be used as an additional marker in combination with other clinicopathologic features for planning the treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
